Retail price is ~$40 each.
It will likely take more than one fixture to get anywhere near the results that you are seeking.
To get the results that we wanted for the back of the house, we wound up using three fixtures.
Was it all worth it? I dunno; kinda, maybe; yeah.
I've always enjoyed the winter snow-cover on our patio and backyard vegetation but often fancifully wondered if holiday lights would be an enhancement. Above is a photo of the remains of our first measurable snowfall for the winter season of 2016 - 2017.
Above is a photo of the laser lights on the snow (the display is just kinda okay without snow).
As we expected, the laser display colors are more subdued when our rear security lights go on.
Even then, we found the effect to be worthwhile.
CAVEAT: The above photo is my attempt to show some of the laser "overspray" that is showing high in the trees, near and far. The point being is that these lasers could be a nuisance to drivers on the road and on the highway beyond the treeline in back of us; we also use care to void anything shining through the windows of houses near and far.
Even at a distance, my eyes find that a quick flash from a beam can be noticeably painful.
